The allegations are a far cry from her upbringing and education at St Olave's, where she excelled.

She achieved four A*s and nine A grades after taking her GCSE exams at St Olave's sister school, Newstead Wood.

She went on to take A–levels in English literature, classical civilisation, geography and French.

While studying she offered her services as a tutor.

Her parents, Robert and Lindsay Johnson, live in a large detached farmhouse in Orpington in Kent. They bought the house, which has extensive grounds and a tennis court, in 2006.

Before moving there they sold their previous house, 10 miles away near Greenwich, for £930,000.

Mr Johnson is a successful businessman, with directorships in several companies. The couple run Avongate, a direct marketing company. Mr Johnson was also a director in a company that took over the Daily Sport and Sunday Sport newspapers in 2007.

Miss Johnson was granted bail on condition that she does not associate with her co–accused, wears an electronic tag, submits to a curfew between 7pm and 6am and does not enter any London postcode. Both her parents were in court to offer her their support.

She is due to return to the court on Sept 21 when her case is expected to be committed to the Inner London Crown Court.

A separate hearing for her co–defendants, a 17 year–old and Alexander Elliott–Joahill, 18, at Camberwell Green magistrates' court heard that four people were in the car that allegedly contained £5,000 worth of electrical equipment and cigarettes and alcohol worth more than £500.

The two were allegedly passengers in the car. Both were denied bail and will next appear on Sept 7. The 17 year–old is to enter the second year of a business degree at Christ the King College in south–east London this September.

He indicated a plea of not guilty to five counts of burglary while Mr Elliott–Joahill gave no indication.

Miss Johnson's entry on a website for work as a tutor says: "My name is Laura Johnson, a sixth form student studying English literature, classical civilisation, geography and French at Saint Olave's Grammar School.

"I was a student at Newstead Wood School for girls and gained four A*s and nine A grades at GCSE. One of my A*s in English which I intend to carry on at university level."
